RAY B. JACKSON, OF EDGEWOOD PARK, E'ENNSYLVANIA, ASSIGNOR TO WESTING- HOUSE ELEO'TRIC 86 MANUFACTURING COMPANY, A CORPORATION OF PENNSYL- VANIA.

INSULATOR.

Application filed March 31, 1920. Serial No. 370,217.

To all whom it may concern:

Be it known that I, RAY P. JACKSON, a citizen of the United States, and a resident of Edgewood Park, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Insulators, of which the following is a specification.

My invention relates to insulators and particularly to suspension insulators.

One object of my invention is to provide a device of the above indicated character that shall greatly facilitate the assembly and readily permit thereplacemcnt of any number of units of which it may be composed.

Another object of my invention is to providea series suspension insulator that shall be simple and'durable in construction, economical to manufacture and effective in operation.

Heretofore, it has been usual, in seriesrelated suspension insulators, to provide cemented-in pins, hooks, bolts, specially constructed parts and various other forms of more or less expensive structures.

In practicing my invention, I provide an insulating member of porcelain or other suitable material that is formed substantially of S-shape, to readily receive a cooperating connecting member at each end, that is also provided with an intermediate web or discoidal surface-creepage portion.

Figure 1 of the accompanying drawings is an elevational view of an insulator constructed in accordance with my invention, and Fig. 2 is a similar view, taken at right angles to Fig. 1. p

A plurality of insulating members '1, preferably of porcelain, although other suitable insulating materials may be employed, are each formed substantially of S-shape having adequate creepage-surface distance and also to mechanically reinforce the members 1.

The assembly or replacement of any number of the members 1 and 4 is an exceedingly simple operation, requiring merely a hooking or unhooking operation and provides, particularly in this respect, greater facility in manipulation than, to the best of my knowledge, has heretofore been permissible in series or chain suspension insulator sets.

lVhile I have shown and described a par ticular form'of my invention, changes may be effected therein without departing from the spirit and scope thereof, as set forth in the appended claims.

I claim as my invention 1. A suspension insulator comprising an insulating member of substantially S-shape having an integral surface-crecpage portion 1ntermed1ate its ends.

2. A. suspension insulator comprising an insulating member of substantially S-shapc having a laterally extending web portion disposed diagonally of the longitudinal axis of the insulator intermediate its ends.

3. A suspension insulator comprising an RAY P. JACKSON.
